Beit knownthat-I, CHARLES HTLDEBRAND, ofi Y'oungstowmfin the county of: Mahoning and State of Ohio, have. Vinvented certain new and useful Improvements in- Measuring' Pumps, ofv which` thet'ollowing is aspecica,

stated, terminates.` iirithin.` 1 a shortl distance ot' the saidtop head, leaving an annular way for ,theoil into. the, reservoir.

This prevents the oilfrom foaming-since its ow is confined in the narrow-annular pas-v sage betweenV the. stock and the,` sleeve. The oil escapes at the; b0ttom`of the sleeve and rises as 'it is pumped.

The pump-stock isA in two sections, which meet in a central threadedl socket ofthe bottom head of the reservoir, and; thusmeans are afforded for properly supporting and sealing the reservoir upon the pump-stock. .v

The bungV through which the pump-stock passes supports the dripping-pan and vesselcarrier, the connection being a pipe,which carries back the drippings into the can or barrel.

A valve'is arranged to prevent they escape of gas from the-barrelor can through the drip.

The bung is chambered to receive 'a metal-v lic packing-collar and a washer for the pumpstock, or any other suitable packing, which packing rests upon the annular seat forming the bottom of the chamber. v

By this construction l obtaina seat for 4both the pump-stock and the drip. An annular chamber is also formed by the pump-stock, and the interior of the bung forms a communication between the drip and the barrel, around the pump-stock.

The measuring-scale. index is a tube, which embraces one of the tension screw-rods of the reservoir-heads, the scale being upon a serrated strip projecting from said tube.A

The drip is mounted upon a tube, which is made adjustable within the bung-hole connection by means of a supporting-clamp iixed by a set-screw, so as to render the drip-tube extensible within the connecting-pipe.

In the accompanying' drawings, Figure l represents an elevation ot' my improved oilmeasnring pnmp,and Fig. 2 a vertical section ot' the same; and Fig. 3, an enlarged section ot' the bung and drip connection.

` The y measuring-reservoir may be made of metal, and be provided with a graduated glass, or its cylindrical portion may be of glass, its heads B B being ot' metal. When of glass, the indicating-scale may be cut in the glass, or, as shown, it may be a serrated langed. tube, p, embracing one of the rods holding the heads B B together.

This reservoir is supported directly upon the pump-stock A, and incloses it in the following manner: The pumpesrock is in two parts or sections, A A', threaded at their adjacent ends, both of'whch meet and become one in a threaded central hubbed socket, a, ot' the bottom head B ot' the reservoir.

When the cylinder of this reservoir is ot'. glass, the metallic heads B B' are secured togather by screw-threaded tension-rods b b, one of which carries the measuring-scale, as

above stated.

The section A of the pump-stock is within the reservoir, but extends upward only within a short distance of the head B, and, when pumping, the oil iiows over and down its outer sides to the bottom of the reservoir.

To prevent the foaming which would result from such a fall, I eXtenda sleeve, D, from the top head B down over the section A', to

within a short distance of the bottom of the reservoir. This sleeve D is ot' greater diameter than pump-stock section A', and, in combination with said section, forms a narrow annular passage for the oil, which retards the tendency to foam, and empties the oil at the bottom ot' the reservoir, from whence it rises to the required index as it is pumped.

The upper head B of the reservoir has a vent, c, with which there can be connected, if necessary, a double-acting valve.

The lower head B is perforated at a?, for the reception of the spigot E and its connection. From this spigot the oil is drawn off into the vessel to receive it, which rests upon the drippingpan l", which is made adjustable by aclamp, d, and screw e, the clamp projecting and supporting the dripping-pan pipe-stem f upon the pipe-connection g, which is an elbowed pipe entering the bung G. At the entrance of the pipe g into the bung is a valve, g', to prevent the escape of gas trom the barrel, which, in this instance, is an automatic ball-valve. Any suitable valve, however, may be used. The oil flows from said pipe g through the opening hin the interior wall of the bung, from whence it flows into an annular chamber, h. between said inner wall and the pump-stock, down into the barrel.

Said bung is chambered to receive a packing-nut, H, and a washer, z', to e'ectually seal the bung-hole-pump stock connection.

The bottom of the pump-stock, which is preferably made in the form of a detachable section, j, as shown, is provided with short spurred or armed legs jj, which, when the pump-stock is inserted into the barrel through the bung-hole, strike the opposite side of the interior of the barrel, and serve to step or steady the instrument, while the free ingress of the liquid into the pump is permitted. This detachable section carries the lower pumpstock valve.

llhe entering end of the bung has a tapering screwthreaded perimeter, k, which permits oi' a tight joint being screwed into the wood.

The pump itself is of any ordinary or preferred construction; but the pump-handle is preferably fulcrumed on arm I, secured rigidly to a collar, l, fastened, by set-screw m, to a cylindrical projection, n, of the head.

The piston-rod J, which enters the pumpstock at this point, has a suitable metallic packing, o, screwing down into said cylindrical projection.

I claim- 1. The combination of the meeting sections A A' of the pumpstock and the head B of the reservoir, provided with a central hubbed screw-socket, a, whereby the said reservoir incloses and is supported directly upon the pump-stock, substantially as described.

2. The combination of the pump-stock section A', the sleeve D, and the reservoir, forming a narrow owway for the oil into the reservoir to prevent foaming, substantially as described.

3. The tubular index-scale p, secured upon and by the tension-rod b, in combination with the reservoir, as and for the purpose set forth.

4. The bung G, having the annular chamber h formed therein below its packing t', and.V provided with the packing-nut H, and the valved connection with the drippan, as and for the purpose herein set forth.

5. The combination of the dripping-pau F with its pipe-connection g and the annular chamber of the bung G of an automatic valve, g', to prevent the escape of gas from the barrel through the drip-openings, substantially as set forth.

6. The combination of the dripping pan pipe-stem f and the pipe-bung connection g of a supporting-clamp, d, and set-screw e, whereby the drip-pan is made extensible and is supported.

7. The combination of the chambered bung G, the pump stock A, nut H, and washer 11, whereby the pump-stock connection is sealed, substantially as set forth.

In testimony whereof Il have afxed my signature in the presence of two witnesses.
